Valid 081200Z - 091200Z

....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm potential will remain low across the U.S. on Saturday.

....Discussion...
The quasi-zonal flow field aloft which has prevailed recently will
remain in place across most of the U.S. on Saturday.  A couple of
low-amplitude short-wave troughs will progress through the
westerlies -- a lead feature initially over the northern and central
Plains, and a second over the Pacific Northwest.

The lead feature will permit a weak frontal wave -- initially over
the Oklahoma/Missouri vicinity -- to shift eastward along the
surface front with time, crossing the Ozarks and Ohio Valley region
through the day, and then off the Mid-Atlantic Coast overnight.

Potential for thunder appears low across the U.S. through the
period.  A lightning flash or two could occur over the Pacific
Northwest vicinity early, as the upper trough crosses the area.  A
few showers are expected across the central Appalachians vicinity,
in a zone of warm advection ahead of the approaching surface low,
but lack of instability should preclude lightning.  Elsewhere, aside
from a few showers and possibly a lightning flash near/off the
Carolina Coast, and likewise across the South Florida/Keys vicinity,
thunderstorms are not expected.
